Are you using QB Online? What kind of accountant changes do you need to import? Why doesn't your accountant access your account directly through their QBO Accountant account?
Hello there, @damond. I'm here to share some details about importing accountant changes in QuickBooks Online (QBO).
In addition to Fiat's questions above, could you tell me if you've already invited your accountant to your QBO company? This process will let them access your file to review your books, make necessary corrections, undo the entire reconciliation, etc. If you haven't yet, you can use this article for the detailed process: Add accountant users in QuickBooks Online.
On the other hand, you can utilize the import feature in QBO, to upload data such as bank transactions, name lists, invoices, etc. Please check this page for a detailed guide: Common questions about importing data to QuickBooks Online.This also includes the list of file formats supported by the program.
